 You can build UTM with the script:
 
 ```sh
-./scripts/build_utm.sh -t TEAMID -p macos -a ARCH -o /path/to/output/directory
+./scripts/build_utm.sh -t TEAMID -k macosx -s macos -a ARCH -o /path/to/output/directory
 ```
 
 `ARCH` can be `x86_64` or `arm64` or `"arm64 x86_64"` (quotes are required) for a universal binary. The built artifact is an unsigned `.xcarchive` which you can use with the package tool (see below).

 ```
-./scripts/build_utm.sh -p ios -a arm64 -o /path/to/output/directory

 The built artifact is an unsigned `.xcarchive` which you can use with the package tool (see below). Replace `ios` with `ios-tci` to build UTM SE.
